Abstract: 846,106. Valves. I.V. PRESSURE CONTROLLERS Ltd. Jan. 18, 1957 [Jan. 20, 1956], No. 1994/57. Divided out of 846,105. Class 135. A fluid-control valve comprises a closure member 2 coacting with a seat 3 to control the sole outlet 7 from a chamber 16, and a passage 10 permenently connecting the outlet with a chamber 5 containing a balancing piston 4 the effective area of which is substantially equal to that of the closure member exposed to outlet pressure when the valve is closed. The closure member, which has radial projections 13 against which bears a closing spring 15, is opened by a control rod 12, and the closure member is slotted at 11 to prevent closure of the passage 10 by the rod. The piston 4 carries a rubber &c. sealing ring 8. The arrangement may be such that inlet pressure acting on the closure member is balanced or contributes a small closing force. The passage 10 may alternatively be formed in the housing of the valve, and when the valve discharges to atmosphere the balancing chamber 5 may be open to atmosphere. In a modification, the spring is housed between the bottom of the chamber 5 and a counterbore in the balancing piston, the closure member consists of an upwardly facing, annular knifeedge, and the control rod is integral with the closure member. The invention may be applied to a pressure regulating valve as described in Specification 846,105.

[Class 38 (iii).] Following movements of control member.- The pressure in a pipe 6 positions the end 3 of a pivoted contact beam 1 to open one of two switches 18, 20, thereby de-energizing one of two normally energized opposed fields 12, 13, of a motor 11, and causing the motor to position a pointer 9 and at the same time move, through a rack and gear 23, 24, a casing 22 carrying the co-operating contacts of the switches 18, 20, so that when the pointer 9 is adjusted to correspond with position of the beam 1, both switches 18, 20, are closed, and the motor is brought to rest quickly under the action of the reverse field. The motor may drive the rotor of a machine 25 having a three-phase winding connected to that of similar machines 26, 27, so that a distant pointer 35 and a recording meter 33 give indications of the pressure in the pipe 6. Instead of the rack and gear 23, 24, a machine such as 25 may transmit to a similar machine which repositions the beam 1.

Title: Timing signal generating system for a printer
IPC: B41J9/10
Filed: 1975-01-17
Abstract: 1441563 Printers DATAPRODUCTS CORP 17 Jan 1975 [17 Jan 1974] 2214/75 Heading G4H A system for generating timing signals for hammer actuation in a printer comprises sensing means 35 adapted to sense the passage of characters along a printing line along which the hammers are aligned more closely spaced than the characters), a phase detector 36 comparing the phases of the output of the sensing means 35 and an output of a ring counter 42 to control the frequency of a voltage-controlled oscillator 40 via filter-integrating means 41, the oscillator 40 driving the ring counter 42. As disclosed, the ratio character spacing (on a typebelt moving along the print line) over hammer spacing is 5/4 so the ring counter 42 has 5 outputs corresponding to the 5 sub-cycles in which respective interleaved groups of characters become aligned with hammers, to control hammer actuation timing. The oscillator 40 frequency is nominally five times that of the pulses from detector 35 which detects slugs 30 on typebelt 10 (one character per slug). Another detector 75 detects only some slugs (e.g. one) to reset counter 42. Variable delays 48, 86 are for initial adjustment. There may be more than one character per slug in which case a division circuit is inserted in the connection from counter 42 to phase detector 36.

Title: Improvements in or relating to percussion fuzes
IPC: F42C15/24
Filed: 1939-01-23
Abstract: 511,019. Ammunition. RHEINMETALLBORSIG AKT.-GES., and WINZER, K. Jan. 23, 1939, No. 2246. [Class 9 (i)] The striker 2 of a percussion fuze is mounted in a plunger 2<1> held in position by a shearing pin 3, and can only be actuated by an impact plunger 5' when a ball 10 becomes positioned between the plunger 5' and the striker. The ball is held in an oblique channel 9, for transport purposes, by a plunger 12, which for purposes of explanation is shown in Fig. 1 as in the same plane as, and diametrically opposite the ball, but which is actually located as in Fig. 2, so as to intersect the wall of the channel 9 at 11 and so partially obstruct this channel. The plunger 12 is supported by a spring 12<1>, and a spring-loaded pin 13 bears against the plunger, so that when the projectile is fired, the plunger 12, owing to its inertia, sets back and is locked in the set back position by the pin 13. The channel 9 is thereby freed and on the descent portion of the trajectory, the ball falls into line with the striker, thereby arming the fuze. Impact during ascent causes the plunger 5<1> to obstruct the channel 9 thereby preventing access of the ball to the armed position.

Abstract: 871,056. Automatic alternator control systems. JACK & HEINTZ Inc. Jan. 23, 1958, No. 2300/58. Class 38 (4). Sharing of the reactive load between alternators 10, 11 is effected by D.C. exciters 20, which feed excitation windings 12, 13, in response to the output voltage across resistors 48 in respective phase-sensitive rectifier networks 36, 37, the networks being fed respectively with a voltage from phase lines B, C and a voltage across resistor 55, 56 resulting from a current unbalance in the two sets of feeders detected by current transformers 30, 31. The potential across the resistors 55, 56 reflects the difference between the two currents and the phase of the signal across the resistors relative to the phase of the voltage in secondary windings 34, 35, determines the output across resistor 48. Voltage control of the individual alternators is also effected by the field excitation in response to the difference between the rectified alternator voltage appearing across a resistor 28 and a reference voltage from a constant voltage source 22. The controlling signals are applied to the exciter through a power amplifier 21. For control of the sharing of the real load on the alternators the voltage transformer 32 is connected between neutral and the phase line, the current of which is measured by current transformer 30. Real output may be controlled by controlling the power input from prime movers 16, 17. Where more than two alternators are controlled the current from one is compared with the average current from the others.

"Bifluid electrolysis" means electrolysis in which a permeable diaphragm separates anolyte from catholyte. The Fig. illustrates the process and also illustrates : (a) prevention of Cr loss with the Fe-containing precipitate arising from the hydrolysis step. (As illustrated, the hydrolysis occurs in the autoclave). (b) prevention of build-up of too much sulphate in the system, e.g. derived from sulphur-containing ores. (c) Treatment of the material not dissolved by the leaching to recover elemental sulphur and other materials therefrom.
